FTP via SSH tunnel problem

Hi all,

I'm trying to setup a FTP session via a SSH-tunnel. I do exactly the same from a linux client and a VMS client (same commands same servers etc..). However the linux client works where the VMS client fails.

My system : OpenVMS Alpha 8.3 TCPIP services 5.6 ECO 2I have both TCPIP$FTP_ALLOW_ADDR_REDIRECT and TCPIP$FTP_ALLOW_PORT_REDIRECT defined to 1 in the system table. and resterted the FTP-client after that.

Re: FTP via SSH tunnel problem

In order to successfully tunnel an FTP session over SSH it is necessary for SSH to recognize the PORT and PASV commands and their responses and make the necessary substitutions just as a NAT device would. It is possible that the Linux SSH code is built with such code and that the TCP/IP Services code is not.

Process Software's SSH software is built with code to recognize FTP tunnels and it generally works better in PASV mode than PORT mode.
